Acute gastritis is characterized by severe nausea and vomiting, usually of stomach contents, and sometimes includes bile. It is also accompanied by significant abdominal pain. In such cases, it is imperative to administer antispasmodic analgesics and antiemetic medications promptly, as well as antibiotics sensitive to the gastrointestinal tract. If the vomiting is severe, it may lead to dehydration, necessitating timely rehydration or intravenous fluid therapy. It is important to maintain dietary hygiene, consume soft, easily digestible foods, and reduce the intake of raw, cold, and spicy foods. Meat should be thoroughly cooked before consumption. Engaging in moderate outdoor physical activities after meals can enhance gastrointestinal motility. (Please use medications under the guidance of a doctor.)
